Big S1ster Blackmail and JOI

You've been stealing my panties you dirty pervert! I put a video camera in your room and found you jerking off with them, and now you are going to do as I say so that I don't tell everyone. You're going to jerk off exactly like I tell you to, and you're not going to cum as quickly as you did in the video! You are going to cum when I tell you to. If you cum early, I am telling everyone how you stole your s*sters panties! I tease you with my armpits, my tits and bush and taunt you with the fact that you'll never get to fuck me, because I am your s*ster.
